Crews from the Prescott Fire Department, Life Line Ambulance, Prescott police, and airport staff all responded to the incident.
The first arriving unit, Foam 73, a specialized Crash Fire Rescue apparatus, found a downed helicopter, on its side, with severe damage.
Two patients were spotted lying on the grass outside of the wreckage. The patients were both designated as Level 1 trauma victims, the highest level of trauma designation, due to the mechanics of the accident itself as well as their conditions.
Based on those findings, additional resources were dispatched to the scene, including a Native Air medical helicopter based in Prescott Valley and a second medical helicopter, Guardian Air, from Cottonwood.
The two male patients, both estimated to be in the 20s or 30s, were assessed, treated, and transported by air to the Flagstaff Medical Center.
The current condition of the patients is unknown.
There was a fuel leak from the wreckage but ignition sources were kept away from the fuel and no fire ensued.
The helicopter is operated by a local flight training company, based at the Prescott airport, but the owner of the aircraft has not been determined.
Witnesses reported seeing the helicopter fall from the sky at an estimated height of 50 feet. The aircraft suffered extensive damage.
There were no injuries to responders.
The NTSB is investigating the crash.
